You may even try these Brembo side mounts that I have on my 2005 Dyna. I have put these on many baggers with our 320 mm SS Floating rotors (3 1/4 Lbs).as well as our MMC (2.2 Lbs.) and adapters which works very well and there is not much of a comparison with the older 11 1/2" rotors/systems. Again, great brake pad material is very important increasing your friction coefficient. You need to think in terms as a complete all around package. Think also about tires.
Another option is the XR1200 caliper which has the exact same internals as the Honda Fireblade. They also share the same brake pads so you can purchase inexpensive great brake material pads all over the world. The mounts are the same as the old style twin cam so they are direct bolt up. If you have some size laced wheels such as a 19" which the bulky caliper will hit the spokes. You can also purchase adapters and use 320mm rotors.
Yes, you can bolt them up to a Bagger or a twin cam Dyna and they cost only $185 at HD.

Add steel braided lines and you will feel an improvement. that is what i am running right now but I plan on adding a PM master cylinder as well. Seeing as a single piston master cylinder has the same bore as the stock mc I don't see how it can improve more. But, the general idea is you have to upgrade the brake line as well as stock lines are known to flex and steel braided lines hold more pressure.
I am going down to PM's shop on Friday and I will ask for more clarification while there.

Drew,
That's the way I understand it also. I have the PM 6 pistons and the braided lines, but I'm still running a HD chrome MC. I have noticed better braking with the set up I got over the 4 piston. My next braking improvement will be the PM MC.

just picked up a set of full floating racing rotors ( NOT the cheap harley crap ) from Motorcycle Metal, Howard, ( who has been posting here as FastHarley ) KNOWS HIS **** about STOP FAST BRAKES
you got a go fast bike,,, you need STOP FAST BRAKES
what he's doing there at MM with Carbon Fiber wheels, the MMC rotors, ect is like light years ahead of the competition
will be bolting on a new set of chrome wheels, along with the MM rotors & a new Brembo front caliper ( again, NOT the harley Brembo option )
will post up some photos then
i'm sure PM makes some good stuff,, but it'll look just like the 20k other bikes that are running it,, NOT for me
thanks Howard for hookin me up

Very easy to install. Did not have to replace any of the stock
OEM parts (Master cylinder, brake line).
Bolts right up...actually gives the brake line a little more slack, but not enough to be noticed.
I bled the brake line myself.. very easy although a second set of hands
would help.
Very good lever feel... much better then stock... Haven't had to do a hard stop yet.. but it does have better stopping power....
Would recommend if you want to upgrade you front brakes.

I increased the front wheel diameter from 16" to 21", felt like boosting the bite on the brakes was a must. Running PM 6-piston caliper, direct bolt on, no mods. Brakes feel solid and more responsive. I brake 70% front and 30% rear all the time.

Forgot about this thread. Well I ordered the PM 6 piston front ,4 piston rear calipers about a month and 1/2 ago.I have put about 700 miles on them since the install.The braking performance is better.It is not OH MY GOD better but you can feel a difference.Stock master cylinder ,ride wright 1 pc. rotors and magnum chromite stainless brake line.The looks are incredible and they are a quality piece.I have no 2nd thoughts about shelling out the $$$$ for this mod.

I was just scrolling through the PM 2011 products catalog and they have some charts that illustrate the difference in stopping distance between their calipers and stock Harley calipers. However the comparisons are fro HD 1 piston calipers vs their 4 piston calipers, and Harley 4 piston calieprs with the 13" rotor and their 6 psiton caliper. Softails have an 11.5" rotor. The difference for the HD 4 piston with 13" rotor vs the PM 6 piston caliper do suggest better stopping though. From 60mph they stopped 39 feet sooner and from 80 mph they stopped 67 feet sooner.
